TL;DR

The issue is likely caused by exceeding the maximum allowed tokens when reading a file, and providing an empty text content block in an API request.

Guidance

• Check the API request payload to ensure that the text content block is not empty.
• Verify that the file being read does not exceed the maximum allowed tokens (10000) and consider using offset and limit parameters to read specific portions of the file.
• Review the error messages to identify the specific file and API request causing the issue.
• Ensure that the current working directory is correct and the file exists in the specified location.

Example

No code snippet can be provided as the issue does not contain sufficient information about the code.

Notes

The issue description is truncated, which may limit the ability to provide a comprehensive solution. Additionally, the errors provided are related to different issues (e.g., AxiosError, MaxFileReadTokenExceededError, File does not exist), which may indicate multiple problems with the code.

Recommendation

Apply a workaround by modifying the code to handle files with a large number of tokens and ensure that API requests contain non-empty text content blocks.
